Water intrusion possibly stopped at one mine next week
“By now, one of the mine workings has been filled with hardening backfill mixture. In the coming week, once the mixture will harden, water valves will be shut and the inflow of groundwater should stop,” said Senior Vice President, Head of Norilsk Division, Nikolay Utkin.
New schedule unlikely until after March 16, 2021
The company said it plans to review the timetable for restoring the two mines once ongoing operations are completed by March 16.
Norilsk concentrator is shut down and being repaired
The Norilsk concentrator is currently completely shut down and undergoing necessary repairs. The company plans to restore the ore processing circuit at the concentrator by March 16 by improving the loading and processing flow. The plant is currently being inspected by the Federal Service for Environmental, Technological and Nuclear Supervision (Rostekhnadzor) and the company’s internal technical auditors. A decision on when to restart the concentrator will be made after these two inspections are completed.
